C.M. Russell Museum Complex is an art museum located in the city of Great Falls, Montana, in the United States. The museum's primary function is to display the artwork of Great Falls "cowboy artist" Charles Marion Russell, for whom the museum is named. The museum also displays illustrated letters by Russell, work materials used by him, and other items which help visitors understand the life and working habits of Russell.
In addition, the museum displays original 19th, 20th, and 21st century art depicting the American Old West and the flora, fauna, and landscapes of the American West. In 2009, the Wall Street Journal called the institution "one of America's premier Western art museums." Located on the museum property is Russell's log cabin studio, as well as his two-story wood frame home. The house and log cabin studio were designated a National Historic Landmark in 1965, and added to the National Register of Historic Places in 1976.
Beginning in 1969, the museum co-hosted the C.M. Russell Auction of Original Western Art—an auction of 19th, 20th, and 21st century art of the American West whose proceeds benefit the museum. The auction has received media attention in Australia, Canada, France, Germany, Japan, New Zealand, the United Kingdom, and the United States. In 2010, the two co-hosts parted ways, and the C.M. Russell Museum inaugurated a new auction, "The Russell."
